Claims. (o1. 225 -2) This, invention relates to attachments. for kegs,barrels or other containers whereby the contents may be tapped. off orrefrigerated or both..- i

The main object. of the. invention. is to provide improved.means-whereby a key,'barrel or other container. may be. readilyand'efijicien'tly tapped.

Aiurther object of the invention is to pro.- vide improved. means.whereby the contents of a keg, barrel or other container may bereadilyand efficiently refrigerated l A further object of the invention is topro videimproved meanswhereby .a barrel or other container may bereadily and efficiently tapped and its contents refrigerated. I

A further object of the invention'iisgto provide means for eflicientlyand readily tapping a keg, barrel or other container whereby thecontainer is maintainedclosed against contamination from the exterior atall times. t

A further object of the invention is to" provide an attachment for kegs,barrels or other containers whereby the container may be readily.

Fig. 6 is a section of the bushing on the line In the accompanyingdraWingwh-ich illustrates the invention, in -the headof thekeglisscrewed a bushing 2 ,having', the. inclinedbayonet slots ,3in'oppostie sides, such. bayonet slots communi-, cating with the upperedge of the bushing by means of axially extending. slots 8, and havingholes 4 inthe diaphragm. constituting its bottom throughwhich theeduction .or cooling pipes may be-extendedintothe keg aswillbehereinafter referred to..- v U 1 In the bottom-of the bushing 2. is alsoa central hole. 5 within which isrotatably mounted thespindle. 6 towhich is secured the valve .1 adapted to be. movedinto and. out ofposition toclose. the holes! by turning the spindle 6. The detachabletapping and cooling attachment .to be applied to. the keg. bushingcomprises. a body portion 9' havingvthe turning Wings 3 4,- andprovided. at.

diametrically opposite points with lugs I 0 adapt ed: tobeentered=within-the slots. 8 and then turned into the slots/3,. theinclination of which will. draw the body tightly against the" upper partof. the bushing,. a gasketl I of rubber, or other suitablematerial,..being compressed, between ,the

body and. the. bushing. to make a tight joint.

Within the. body ,s all two, bores, I2 and l3 within whichlongitudinally slidethe tubes I4 and I5. Both'of these tubes and their-manner of operation may be precisely alike,..when, they may both beeduotion tubes for thecontents of.

the keg or. barrel, as for instance they may lead,

from theinterior of a keg to.a,. plurality of faucets.. In the structureshown, however, one of the tubes, namely I5, is used for cooling orrefrigerating purposes as will, later appear. The tubes l4 and I5 arerespectively surrounded by gaskets I 6 and I1 which are compressed'bythegland nuts I B and I9 having turning wings 20' and 21 at their upperexposed sections. c

When the gaskets l6 and llarecompressed' they will bear tightly againstthe pipes 14 and 66 of Fig. 5, the other parts being omitted; and

Fig. 7 is a fragmentary view showing a portion of the' attachment inside elevation and a I5 so that a fluid-tight joint is formed butlongitudinal sliding of the tubes and. l5iis permuted;

Threisaclearance in the bore l2 about the pipe I4 such clearancecommunicating through a passage 22 with a source of'co'mpressedainsuohpassage beingcontroll'ed' by thecock 23. The air v 1 under pressureii'sadmitted to the. urface of the liquid in the keg; to afford. pressure toeject the liduid,'from the bore l2'to the interior of the bushing 2 andthence through the" holes 4 (when uncovered by the valve 1) intotheinterioro'f the keg above'theliquid.

The: pipe' [4" is adapted to be attached at. its

fluid, which pipe communicates through the controlling cook 29 with anysuitable source of cooling or refrigerating fluid. The pipe 28 extendsto a point adjacent the lower end of the pipe so that the cooling fluidpassing downwardly through the pipe 28 will issue from'the end thereofand then pass upwardly within the pipe I5 and about the pipe 28 toanexit pipe 30' at the upper end of the pipe l5.

The lower end of the pipe 28 is closed in fluidtight fashion by means ofa tip 3| screwed therein, such tip being similar tothe tip 25 but havingno openings therein to communicate outside the pipe IS, the tips 25 and3| being of substantially the same exterior configuration.

The body 9 is provided with a socket 32 of square cross section whichisadaptedupon the inception of the attachment of the body to the bushing,to permit the end 33 of the valve spindle. which end is of square crosssection, to. enter within it. The turning of the body 9 to' secure it inthe bushing will then turn the valve so as to uncover the openings 4.Conversely the turning of the body 9 to detach it will cause the valve 1to closethe holes 4 in a fluid-tight manner.

The tips 25 and 3| are of such diameter that they will pass through theholes 4 but will not pass through the bores l2 and I3. This permits thepipes l4 and I5 to beslid longitudinally out- I wardly until the tips 25and 3| are in the bushing (see Fig. 2) when they will not interfere withthe movement of the valve 1 to close the openings 4 and at the same timewithdrawal of the pipes l4 and I5 from the body 9 cannot be effectedwithout unscrewing and removing the tips 25 and 3|. This prevents thedisassembly of the pipes and body accidentally or withoutafixedpurposeto doso. g f j In operation theplpes l4 and |5'will be'slid inwardly until their inner ends are adjacent the this position itwill be seen that the cooling fluid traverses the liquid in the kegsubstantially from top to bottom and that the air pressure on the top ofthe liquid forces it into' the lower end, of the pipe 4 whence it istransmitted to the tap or serving faucet.

Ordinarily the tapping and cooling attachment.

were applied, the lugs l0 would be entered within the slots 8 and thespindle end 33 in the socket 32. Turning of the body portion 9 totighten it in the bushing by means of the inclined bayonet slots 3 wouldturn the valve 1 so as to uncover the openings 4. Air pressure wouldthus beadmitted through the openings4 to the top surface ofthe liquid inthe container. The pipes l4 and I5 would then be pushed inwardly untiltheir lower ends were adjacent the bottom of the keg (see Fig. 1), thecooling fluid entering through the tube 28 and passing upwardly in thetube l5 substantially from the bottom to the top of the liquid in thekeg whereby an efficient cooling or refrigeration is efiected. Furtherthe air pressure on the surface of the liquid forces the liquid inthrough the tip and up through the tube |4 under any desired eductionpressure (depending upon the air pressure applied), controlled by theservice tap.

, When it is desired to remove the attachment the tubes l4 and |5 areslid longitudinally outwardly until their tips 25 and 3| are within thebushing 2. The turning of the body 9 todetach it from the bushing 2,will then turn the valve spindle so that the valve 1 will close theopenings 4. The keg, therefore,.when emptied, will always beautomatically tightly closed against the ex- I terior so that no dirt,insectsor other foreign 4 bottom or lower head of the keg (seeFig. 1).In

objects can enter the keg while it is empty and thus deleterious foulingof the interior of the keg is prevented, the keg always being closed tothe exterior except when'it is opened for cleaning and filling at thebrewery or when it is in operation of having its contents removed atthedispensing point.

While the invention has been illustrated in what is considered its bestapplication it may have other embodiments without departing from itsspirit and is not thereforelimited to the structure shown in thedrawing.
